In this paper, we investigate the optimal error estimate and the superconvergence of linear fifth order time dependent equations. We prove that the local discontinuous Galerkin (LDG) solution is ( k + 1 ) th order convergent when the piecewise P k space is used. Also, the numerical solution is ( k + 3 2 ) th order superconvergent to a particular projection of the exact solution. The numerical experiences indicate that the order of the superconvergence is ( k + 2 ) , which implies the result obtained in this paper is suboptimal. |
